I have a 86 gt that i bought with no trans, in it but i decided to put a comp c4 trance with a 3500 stall because I was going to use as a drag car. But since then I have changed my mind and want to keep it on the street and I am not sure if that trans will work for the street. it donest have a od i was wondering if thats something I can install later of not. But i have 4:10 gears in the rear but that screams when driving on the road so i think i am goin to switch to 3:73. If you know what I should do please let me know i am stuck on what to do.
